Very cool! I was just recently feeling that I have LCD fatigue, and wondered what it would be like to have a mobile computing device with a similar screen as a Nokia from 20 years ago.
Can I ask why you copied the classic Blackberry keyboard almost entirely? Even the symbol on the "Menu" button is BB's. There are keyboard phone OEMs like Unihertz that specifically changed their keyboard design to not resemble BB so as to avoid patent disputes.
This is almost certainly an actual BlackBerry keyboard. There have been a number of recent hobbyist projects using them, I don't know if they're old parts lying around warehouses or gutted from unsold phones... but they're out there.
